Lostsunrise [7]

Option D: \frac{2}{5} is the x-coordinate

Explanation:

It is given that the coordinates of the line segment are A(3,2) and B(6,11).

Since, the line is partitioned by the point C by the ratio AC : BC = 2 : 3

The distance between the x-coordinates is 3 units.

To determine the value of the x-coordinate for point C, let us divide the value of x-coordinate from the ratio divided by the sum of ratio.

The value of x-coordinate from the ratio is 2.

Sum of the ratio is 2 +3 = 5

Thus,

The x - coordinate = value of x-coordinate from the ratio / Sum of ratio = 2/5

Substituting the values, we have,

The x - coordinate of the Point C = \frac{2}{5}

Thus, Option D is the correct answer.

A scientist measures the angle x and the distance y between the Earth and the Sun. Using complete sentences, explain how the sci
yanalaym [24]

Answer:

The scientist can use only the angle x and the distance y to calculate the distance between the Earth and the Sun using the cosine function.Step-by-step explanation:

The cosine of an angle is equal to the ratio of the length of the adjacent side and the length of the hypotenuse. In equation form:

cos x = BC / y

Solving for BC

BC = y cos x

BC is the distance between the Earth and the sun

Over [174]

A percentage is a way to describe a part of a whole. such as the fraction ¼ can be described as 0.25 which is equal to 25%. Bea's total will be $33.40.

<h3>What are Percentages?</h3>

A percentage is a way to describe a part of a whole. such as the fraction ¼ can be described as 0.25 which is equal to 25%.

To convert a fraction to a percentage, convert the fraction to decimal form and then multiply by 100 with the '%' symbol.

Given that Bea orders a drink that costs $2.50, an appetizer that costs $8.50, and a sandwich that costs $15.30.

Cost of the order

= Cost of a drink + Cost of an appetizer + Cost of a sandwich

= $2.50 + $8.50 + $15.30

= $26.3

Also, she needs to pay 7% sales tax and 20% tip, therefore, in total, we can write,

Total cost

= Cost of the order + 7% of Cost of the order + 20% of Cost of the order

= $26.3 + 0.07($26.3) + 0.20($26.3)

= $26.3 + $1.841 + $5.26

= $33.401 ≈ $33.40

Hence, Bea's total will be $33.40.
